WATER-GATE.

SPECIFICATION forming part of Letters :Patentl No. 240,564, dated April 26, 1881.

Application tiled January 7, 1881. (No model.)

To all whom it may concern: i

Be it known that I, LYMAN S. WARE, of the town and county of Norfolk, and State of Massachusetts, have invented a new and .useful Improvement in Fiume or Sluice Gates; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure l is a front elevation, Fig. 2 an edge view, Fig. 3 a vertical section, and Fig. 4 a transverse section, of a gate and its supporting-frame provided with my invention, the objects of which are to enable the gateto be easily moved under the pressure of water against it, and to prevent wear of the jointsurfaces of the gate and its support-frame.

Fig. 5 is a rear elevation of the gate, and Fig.

6 is a front elevation of its supporting-frame.

My said invention consists in the combination of a sluice or flume gate, provided with edge and top iianges, with its supportingframe, having ed ge-guides,friction-rollers, and a top flange, all being arranged substantially as set forth.

In the drawings, A de otes the gate, and B its supporting-frame, eac being supposed to be of metal or other suitable material. The said gate has projecting from its opposite parallel and longer edges two anges, a a, each being at a right angle to its edge of the gate. There also projects from the gate, at its upper end, and back from the rear face of such gate, a flange, b, which, at each extremity, extends somewhat beyond the next adjacent longer edge of the gate, such being as shown in Fig. 5.

The gate-frame B has on its front face two parallel guides, c c, their distance apart being to correspond wit-h the width of the gate, such gate being arranged directly between them and by them, and guided by them in its rectilinear movements. In each of these guides, or arranged with them, as shown, is a series of friction-wheels, d, against the peripheries of which the edge flanges a a of the gatebear.

Extending between the guides c c, and from the top of oneto that of the other of them, and projecting from the front face of the gatesupport frame, is a iiange, c, upon the top of which, when the gate is closed, the top flange of such gate rests.

When the gate is shut its lower end is to rest upon a sill or flan ge, f, extending from one to the other of the guides.

The gate-frame may be provided with holes g, to receive bolts or spikes, for securing it to a ilume or sluice.

From the above it will be seen that when the gate is closed, or when more or less open, or while it may be in movement, there will be no material pressure and friction of the jointsurfaces of its longer edges against the guides, the pressure of water on the gate causing the edge iianges to bear on the peripheries of the friction-wheels, whereby, when the gate is in 'the act of being either raised or lowered, it

can be With little power and friction, in comparison to what would result were the iianges to bear directly against the guides unprovided with friction-wheels.

Thus, with my improvement, a gate can be worked to great advantage with little friction and wear of its joint-surfaces, and by a small expenditure of power, comparatively speakin g.

The guides c c may be applied tothe frame B so as to be adjustable relatively to the bearing-edges of the gate, in order to admit of such guides being set up to the gate as it or they may become worn. l-

I am aware of the arrangement of `friction- Wheels and a gate within a sluice, as shown in the United States Patent No. 234,996, and do notclaim such,for such shows no sluice-gate provided with edge or top flanges arranged with it, as are the edge anges a a and top ilauges, b, of my improved gate. Nor does the said pendently of the sluice, and having guides, a top iiange, and friction-rollers arranged in it, and to operate with a gate having edge iianges and a top ilange, as hereinbefore described, and as represented in the accompanying drawings.

With my improvement the devices for supporting and guiding the gate are wholly outside of its vertical edges,and are not in the sluice` or flume to obstruct the water in passing into such. As my invention involves a gate-sustainingframe to be fastened to a ilume, the top flanges, b and e, of such frame, and the gate' become essential to the rest, no such flanges being shown in the said patent. There fore,

patent show any gate-supporting frame inde- I claim- 1. The fiume or sluioe gate provided with the edge and top anges, a a b, in combination with the gate-supporting frame, having the 5 guides c, top flange, e, and friction-Wheels d, all being arranged and adapted substantially as set forth.

2. The ume or sluice gate provided With the edge and top anges,a ab,in combination with the gate supporting frame, having the 1o gnidesc, top flange, e, bearing-sill f, and friction-rollers d, all being arranged and adapted substantially in manner and to operate as set forth.
